ComboBox, no item can be selected

I fill a ComboBox at runtime before showing it.
The box is empty; clicking the dropdown button shows the items, but no item can be selected.
Even when I set TopIndex to 0, the box remains empty.

What's wrong ? The ComboBox is not data bound.
It was once, but the data control was removed,
and the fields "DataField", "DataFormat", "DataMember" and "DataSource" are all empty.

I'm sure you've checked this, but...have you checked the Locked property?

Using .text property from combo control could helps.

As GregJennings sugests, you will get that effect if the ComboBox .LOCKED property is set to True.

Thank you all! It was the Locked property, and Greg was the first one to give the hint, so he gets the points.

I had interpreted "Locked" as a property that prevents a user from typing custom text into the combo box control ... now I know this was wrong.

It is also possible but not by Locked Property; (You may already know this)

DropDown Combo Style prevents a user from typing custom text.
